Kim Kardashian and Kanye West locked themselves in a toilet at the GQ Men of the Year Awards yesterday, WA time.
The couple - who have 13-month-old daughter North together - went missing from their table at the awards ceremony at London's Royal Opera House and were found locked in a disabled toilet just moments before Kardashian, 33, was due on stage to pick up her gong for Woman of the Year.
"We don't know if they were fighting or doing something quite different, but they came out looking very flustered," a source told The Sun newspaper.
"Nobody minded what they were getting up to as long as Kim was on stage in time to get her award."
The incident comes after Kardashian - who rose to fame after making a sex tape with ex-boyfriend Ray J - spoke about her "amazing" relationship with West, 37.
"My husband and I have an amazing sex life," the brunette beauty told GQ magazine.
"So far as the sex tape is concerned, whether or not we've made another - if we have it's never something I want to go public.
"Not something I would want anyone else to see but me and Kanye."
She added: "I'm married to an incredible man and let's just say we like to have fun. Have we made another? There's nothing wrong with being adventurous, having fun and experimenting. What we do privately is private."
